I am interested in ocean biosphere-atmosphere interactions in the Earth System. For nearly 30 years, I have investigated the biological and environmental actors that govern the production and emission of volatile sulfur from the ocean, which I have recently extended to other volatile compounds and gel-like substances. I like to look at both sides of the ocean-atmosphere interface and follow the path of oceanic emissions into aerosols and clouds.
I am also interested in chemical communication between marine organisms, and how this communication shapes trophic interactions and symbioses.
For my research I count on a network of collaborators and use a broad array of methodologies, from “single-cell biogeochemistry” and omics, and trace gas and aerosol measurements, through experimental plankton physiology and ecology, all the way up to satellite analyses and modeling of the global ocean and atmosphere. I have conducted fieldwork in the Arctic, Antarctica, across the Atlantic, tropical Pacific and Mediterranean Sea.
